Replacement glass diffuser for Paulmann LUENA luminaire 180 x 80 mm

Replacement glass diffuser for Paulmann LUENA luminaire 180 x 80 mm is a purpose-made light-transmitting cover intended to restore or maintain the original optical performance and appearance of compatible LUENA fixtures. The diffuser protects the internal lamp and reflector while providing an even, softened light output. It is designed to match the shape and dimensions of the luminaire and to integrate seamlessly with existing mounting points for repair or refurbishment tasks.

Advantages

The glass diffuser offers uniform light transmission and reduces glare through its smooth, translucent surface, helping to maintain consistent illumination across the fixture's coverage area. As a direct-fit replacement it preserves the luminaire’s original look and mechanical fit, avoiding the need for modifications. Its glass construction resists yellowing and maintains optical clarity over time compared with some plastics, supporting long-term light quality and aesthetic stability.

How to use

Before installation, ensure the luminaire is powered off and cooled. Remove the old diffuser carefully by releasing any retaining clips or screws, taking care not to damage the fixture. Position the new glass diffuser into the mounting frame, aligning it with the original attachment points, then secure it with the original fasteners or clips. After installation, restore power and verify even light distribution and secure fit. Handle the glass by its edges and wear gloves if necessary to avoid fingerprints or breakage during fitting.

Usage recommendations

For safe handling and optimal performance, clean the diffuser periodically with a soft, lint-free cloth and a mild glass cleaner; avoid abrasive cleaners or pads. Inspect mounting clips and seals during replacement to ensure a stable installation. If the fixture uses specific gaskets or retaining hardware, reuse original parts where possible or replace with manufacturer-approved components.
